Basic level of C++ programming language is required :

  • basic/syntax: if statements, loop constructs functions, pointers, references, passing function arguments

Geant4 Installation

The hands on will be done on the classroom computers (MAC OSX) with the Geant4 software already installed. If participants want to work with their laptops, it is necessary to install Geant4 before start of the course. No support for installation will be provided during the course.  Also no support will be provided for Windows OS.

More detailed instructions about the necessary Geant4 configuration are available here.
